$8,000,000 is our expected contribution to the "expenses". The actual launch
cost is in the hundreds of millions.

That's what Cubesats offer... ability to launch "off the shelf" satellites
whenever an opportunity comes along, without having to do detailed integration
with the launch vehicle.   If only they were not so damn small...

Even the SpaceX test flights are booked with paying customers. There are no
free rides anymore.

ESA and Ariane did accept that offer, three times no less with AO-10, AO-13
and AO-40. Miracles are sometimes possible but they are quite rare.

>>Could a 3U cubesat with deployable solar panels power a 1 watt, 100 kHz,

Yes, I believe that is possible, with deployable arrays we might even be able
to do ten watts, but such a tiny satellite in such a high orbit will require
big antennas on the ground just to hear it. I can already hear the cries on
amsat-bb about the "elitists" who want to push the little guys out of the
satellite game so they can keep the HEO satellite all to themselves.
